fde4e2f732 HID: fix suspend crash by moving initializations earlier
Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().

fddb33f2e8 HID: sony: fix sony_set_operational_bt
Don't send the report type as part of the data, this prevents the
controller from going into the operational state at all.

This is completely equivalent to what the code originally meant to accomplish:
as per in net/bluetooth/hidp/core.c::hidp_output_raw_report(), by using
HID_FEATURE_REPORT here, what will be actually sent is
(HIDP_TRANS_SET_REPORT | HIDP_DATA_RTYPE_FEATURE) which is exactly 0x53.

2170c5a8ae HID: ntrig: Emit TOUCH with DOUBLETAP for single touch
I squelched TipSwitch in a recent patch which resulted in the loss
of Touch events for single touch firmwares.  This patch just puts Touch back
in for single touch, and bundles it with DoubleTap (like the multitouch code).
The two events are used to convey the same message to different drivers.

336f5899d2 Merge branch 'master' into export-slabh 2010-04-05 11:37:28 +09:00
Tejun Heo
5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

When dumping /sys/kernel/debug/hid/$device/events '\0' characters show up
(invisible if cat to console but shown by less or while looking at a dump
 file).  These are due to hid_debug_event() adding strlen()+1 bytes to the ring
buffer (e.g. including the trailing '\0').  Any roll-over causes a '\0' as well
as hid_debug_event() handles the ring buffers with HID_DEBUG_BUFSIZE-1 size
while hid_debug_events_read() handles it with full HID_DEBUG_BUFSIZE size.

dbf2b17de5 HID: hid-ntrig: multitouch cleanup and fix
This cleans up the identification of multitouch groups and enables
the end of group sync.

Taps are now explicitly handled to adjust for the changes in the
event stream in multitouch mode.  Added triple and quad tap for the
benefit of tools that recognize different tap types but do not have
full multi touch support.

This cleans up the behavior particularly for the latest firmware, which
didn't work particularly well with the older version of the driver.

In this form, when multitouch is active, both mt and st events will come out of
the "N-Trig MultiTouch" device.  And when its not st events will come out of
"N-Trig Touchscreen".

128537cea4 HID: add a device driver for the Apple Magic Mouse.
The Magic Mouse requires that a driver send an unlock Report(Feature) command,
similar to the Wacom wireless tablet and Sixaxis controller quirks.  This turns
on an Input Report that isn't published in the input Report descriptor that
contains touch data (and usually overrides the normal motion and click Report).

Because the mouse has only one switch and no scroll wheel, the driver
(under control of parameters) emulates a middle button and scroll wheel.
User space could also ignore and/or re-synthesize those events based on
the reported events.

Some user-space tools to talk to the mouse directly (that is, when it is not
associated with the host's HIDP stack) are at

2dbf209d7a HID: make full-fledged hid-bus drivers properly selectable
For historical reasons, we don't have most of the in-tree
drivers residing on hid-bus properly selectable in kernel
configuration unless CONFIG_EMBEDDED is set.

This has been introduced on Linus' request from 14 Oct

===
As to the Kconfig options - do they really add so much space that you need to
ask for the quirks? You didn't use to. Can you make the questions depend on
EMBEDDED, or at least on the HID_COMPAT thing or whatever?
===

This still makes perfect sense for small and tiny drivers, which
just fix report descriptors, fix up HID->input mappings that slightly
violates HUT standard, send one extra packet to the device that is
needed before it becomes functional, etc.

Since then, we have been gathering more and more HID-bus drivers,
which are full-fledged drivers. For these, the size argument becomes
more valid. Plus the devices are much more special than "just violates
HID specification in this one or two tiny unimportant points".

Therefore I am marking such drivers as properly selectable no matter
the setting of CONFIG_EMBEDDED, while keeping all the small and tiny
ones compiled by default.

46a709b900 HID: Implement Wacom quirk in the kernel
The hid-wacom driver required user-space to poke at the tablet
to make it send data about the cursor location.

This patch makes it do the same thing but in the kernel.

d4bfa033ed HID: make raw reports possible for both feature and output reports
In commit 2da31939a4 ("Bluetooth: Implement raw output support for HIDP
layer"), support for Bluetooth hid_output_raw_report was added, but it
pushes the data to the intr socket instead of the ctrl one. This has been
fixed by 6bf8268f9a ("Bluetooth: Use the control channel for raw HID reports")

Still, it is necessary to distinguish whether the report in question should be
either FEATURE or OUTPUT. For this, we have to extend the generic HID API,
so that hid_output_raw_report() callback provides means to specify this
value so that it can be passed down to lower level hardware drivers (currently
Bluetooth and USB).

8127f4e883 HID: use multi input quirk for eTurboTouch touchscreen
This device generates ABS_Z and ABS_RX events, while it should be
generating ABS_X and ABS_Y instead. Using the MULTI_INPUT quirk solves
this issue.

1c3a02c215 HID: add NOGET quirk for Prodige Cordless Combo
I happen to own a keyboard identified as 05af:3062 which is labeled as
"FlatX Coldless Combo" by "Prodige", which exhibits input problems without
NOGET quirk. For some reason, lsusb reports this device as "Jing-Mold
Enterprise Co., Ltd", which is not mentioned anywhere on the package.
A quick search on the intenet shows that there a other people who have
this in their lsusb output, but apparently they don't have the problem
I am seeing (or they are not such furious typists as myself).
